Two batteries, one of emf 18 volts and internal resistance `2 Omega` and the other fo emf 12 volts and internal resistance `1 Omega`, are connected as shown. The voltmeter `V` will record a reading of

15 volt

30 volt

14 volt

18 volt

Text Solution

Verified by Experts

The correct Answer is:

`i= (18 - 12)/(2 + 1) = 2 A`
`V_A - V_B = 18 - ixx 2 = 18 - 2 xx 2 = 14 V`
Reading of voltmeter `= 14 V`.
